STMicroelectronics VND5160AJ-E

Overview

VND5160AJ-E from STMicroelectronics is a double-channel high-side driver IC with integrated analog current sense, designed for automotive resistive, inductive, and capacitive load control where one side of the load connects to ground. It features 160 mΩ max on-state resistance per channel, 5 A typical current limitation, 4.5–36 V operating supply range, and CMOS-compatible 3.0 V logic inputs-enabling direct MCU interfacing in body electronics and lighting modules.

For engineers reviewing the VND5160AJ-E datasheet, VND5160AJ-E pinout, VND5160AJ-E application, or VND5160AJ-E equivalent, key selection criteria include its dual-channel thermal shutdown with auto-restart, proportional current sense accuracy across –40°C to 150°C, reverse battery protection support, and ISO7637-2 Pulse III/IV transient compliance for 12 V automotive systems.

Technical Context

The device implements two independent VIPower M0-3 high-side switches with active power limitation during inrush, self-limiting fast thermal transients, and undervoltage lockout at 4.5 V (with 0.5 V hysteresis). Each channel integrates a precision current-sense circuit delivering I_SENSE = I_OUT/K, where K varies from 260 to 750 depending on load current and temperature.

Diagnostic functions include thermal shutdown indication via STATUS pin behavior, current sense disable via CS_DIS (CMOS-compatible active-high), and low-leakage (<1 µA) sense output when disabled. Protection architecture covers overvoltage clamp (41–52 V), loss-of-ground/loss-of-V_CC detection, and electrostatic discharge resilience (4 kV HBM on INPUT/CS pins).

Key Specifications

Pinout & Package

Delivered in PowerSSO-12™ package (exposed die pad connected to V_CC), this 12-pin surface-mount device uses a thermally enhanced layout with dual V_CC pins (pins 7 and 12) and dedicated GND (pin 3) for reverse-battery protection network integration.

FAQ

What is the maximum continuous output current per channel under 85°C ambient?

At 85°C ambient with 1-layer 2 oz copper PCB (per Figure 29), the VND5160AJ-E supports 3.2 A continuous per channel before thermal shutdown activates. This assumes one channel active, 13 V V_CC, and proper thermal vias under the exposed PowerSSO-12™ pad. Derating follows R_thj-amb = 45 °C/W in that configuration.

How does the CS_DIS pin affect current sense accuracy and power consumption?

When CS_DIS is high, the CURRENT SENSE pins enter high-impedance state with ≤1 µA leakage, eliminating sense-related supply current. When low or floating, the sense circuit activates with ±13% K-ratio drift over temperature; accuracy is optimized at I_OUT ≥ 0.35 A where dK/K drops to ±4%.

Can VND5160AJ-E drive inductive loads without external flyback diodes?

No external flyback diode is required for demagnetization because the device integrates an active V_CC clamp and output voltage drop limitation (25 mV at 30 mA). However, for inductances >20 mH or peak currents >1 A, external RC snubbers are recommended to limit dV/dt-induced EMI per Figure 27.

What PCB layout practices ensure optimal thermal performance in PowerSSO-12™?

Use ≥4 thermal vias (0.3 mm diameter, filled or plated) directly under the exposed PowerSSO-12™ pad, connecting to an internal 2 oz copper plane. Maintain ≥1.5 mm clearance from GND pour to avoid parasitic capacitance. Route INPUT and CURRENT SENSE traces away from noisy power paths to preserve analog sense accuracy.
